EXPANDING CARRIER-SPOOL.

mimosa.

-'0 all when, it may con/fern Be it known that I, Lonalszo ZizNi, a citizen of the United States, residing at Scranton, in the county of Lackaivanna and State of Pennsylvania, have invented certain new and useful Improvements in Expanding Carrier-Spools; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to ivliich it appertains to make and use the same.

This invention relates to new and useful improvements in carrier spools `for devices Such as are employed in rotatably si'ipporting skeins ot silk thread, while they are being univoiind.

The particular object of this invention contemplates the provision of a carrier spool equipped with a plurality ot' radial spokes, each of which is provided with a slidable spring pressed spoke head.

A further object is to provide means for drawing in the spoke heads to produce a reduced circumference ot the spool, so that the skein may be placed on the spool and the spoke heads thenreleased, so that by action y ot the spokes pivotally connected to them,

the spoke heads Will then be extended, increasing the diameter of the spool so that all play or slack in the skein is taken up.

A still further object is to provide a simple device for locking the spoke heads in reduced position.

The above and additional objects are accomplished by suchmeaiis as are illustrated in the accompanying drawings, described in the followingr specification and then more particularly pointed ont in the claims which are appended hereto and form a part oi. this application.

With reference'to the drawings. wherein have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views ot which similar reference numerals designate co1'- responding" parts: Figure 1 is a side elevation of the carrier spool illustratingr the 'Spring pressed rods in extended position.

Fig'. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line SW3 of Fig. Q. Fig. il is a detail view ot the locking* device employed in holding;r the spring' pressed rods,

in contracted position.

Proceeding now to the description ot' the drawings, the numeral i, designates the hub ot the spool which is keyed on the spindle 2, the terminals of which are reduced in the Specication ofV Letters Patent..

usual manner as at 3. A plurality of radial spokes 4 are carried on the hub 1 and are provided at their outer free ends with longitudinallyextendino' bores in whiclrare slidably mounted roc s or plungers 5. The members 5 are limited for slidingr movement in the hores by laterally extendingpins 6,

. which yoperate in longitudinal slots Tiformed in the member 4. Each of the members 5 is headed and carries a U-shaped head 8 which is formed of any desired type of light, metal and is designed to receive the skein ot' silk or4 thread.

As a means for normally holding the members 5 in extended position, there has been provided tivo of link members, the individual faces ot one series beingr designated by the numeral 9, and the lindividual 'l'aees of the other series beingdesignated by, the numeral 10. The members 9 and .l0 are arranged in a manner similar to the spokes of -an ordinary bicycle wheel. The members AlO'are all arranged on one side of the hub, while the members 9 are all arranged on the other side of the hub. Each o'f the meinbers l() is pivotally connected at its upper terminal to one of the headed portions of a member 5 as at l1, and is pivoted at its other terminal to a cup member 12, by a pivot pin 13. The member 19. includes a hub 14, a disk plate 15 and an annular rim or Vflange, 1G. The cup iii' arranged with its flange 16 adjacent the hub l ot the spool. The members 9 are connected in a similar manner at their upper terminals to` the headed portions S of the members 5, and are connected at their lower terminals to the pins 17 carried interiorly of the'disk plate of a cup member 18. similar in construction to the member 12 arranged on the opposite side of thehub. v i

lnteriorly of the cup members 12 and `18 are arranged a pair of coil springs, respec tively designated by the numerals 19 and 2O.`

pins 21 and :22 carried on opposite sides of Patented Oct. 6,1914;

thc huh edge and respectively projecting` into the cups 12 and 18. The springs are designed to lnormally hold the members 9 and 10, and consequentlythe members in extended position, and are also designed to hold the members?) into contracted position when the cup members 12 andlS are rotated in opposite directionsagainst the tension of the springs 19 and 20. As a means for 'size on: the spool.

holding vthe cup members in adjusted position against the tension of the springs 19 and 20, when the members 5 are drawn into the spokes 4 in adjusted position, there has been provided a pin 23 carried' on the spindle 2 and extending radially therefrom.

A collar 24, a segment of which is cutaway, as indicated in Fig. 4@his tinged on the outer face of the disk plate 15 is arranged for yrotation on the spindle 2. The pin 23 normally abuis the edge 25 of the collar 24, but is designed to be inserted in a recess formed in the plate 15, when the cup 12 has been rotated through anfapproximate are oi degrees.v The other terminal 27 of the collar 24 limits, in conjunction with the terminal 25, the movement of the cup 12 by engagement with the pin 23. 1n locking the cup 12 in adjusted position against the tension of the spring 19, the pin 23 is inserted in the recess, it obviously iollows that when the pin 23 is seated in the recess, the cup 12 will ybe held against ro-v tation. A similar device, designated as an entirety by the numeral 28, is provided for the cup 18, and need not be described in detail. i i

From the foregoing, the 'operation of the device will be apparent. lWhen applying;

the skein otv silk to the spokes, it is only.- necessary to rotate the cup members 12 and 18 in opposite directions with the resultant reduction of the circumference of the spool as described by a circle passing through the spoke heads 8. When the skein is slipped Into the spoke heads 8, the members l2 and 18 are released and the springs 19 and Z0 again force the members 5- out, thusin-f creasing the circumference of the spool and taking up all slack in the skein.

Relatlve to theanany advantages resident .in the novel form of structure employed in this invention, it is desirable to emphasize the fact that this spool may be employed with any size of threaded slrein by merely changing the length of the spokes, or varying the length of the slits therein. The variation in the circumference oi' the spool comprehended by the various spoke heads, may also be accomplished by employing' spoke rods of di'erent lengths. lty has been found desirable in practice to have several 'sets of spoke rods of diderent lengths, so that they may be readily enlarged when the operator desires to' place skeins of diilerent As negards the advantages of this spool, it is also to be observed rthat the lmotting of the thread or silk is ef fecively guarded against by reason ofthe 'fact that there is no slack Whatever, dueto the action of the springs which the rods in extended position.

In reduction toA practice, l have found thatl tend toflreep misses the form of my invention,.illustrated in the i drawings and referred to in. the above de'- scription, as the preferred embodiment, is the most eicient and practical; yet realising that the conditions concurrent with the adoption. oi my device will necessarily vary, l desire to lemphasize the fact that varices minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing of the advantages oi my invention, as'deined in the appended claims.
